Here is a common question with single replacement reactions:

Explanation:

Given: #Zn(s)+H2SO4(aq)→ZnSO4(aq)+H2(g)#

#color(purple)("Can this reaction take place?")#

Well, let's see:
Castle Learning Chemistry Table J

In this equation, we need to see if #Zn# can replace #H_"2"#.
If an element is #color(purple)("higher")# on Table J than the element it is attempting to replace, then the reaction can happen.

So, is Zn higher than H?
#color(blue)("Yes!")#

Therefore, this reaction can happen.

Another question may ask something like:
Which element can NOT replace #H_"2"#?

The answer has to be something lower on the table (less active) than Hydrogen. The only viable answers are #Cu, Ag, Au#.

Hope this helps!
